Is it normal that Qi Jun always clicks when he steps on the brake pedal?

Give you the common faults of this car together, hoping to help you:

Common faults and treatment methods of Dongfeng Nissan Qi Jun assembly

1, failure of plane bearing (also called steering pressure bearing). The common phenomenon in Qi Jun is that the front wheels rattle when they hit the direction. The reason is that there is something wrong with the design of Qi Jun plane bearing, and the dust is not good, and the lubrication fails after dust and water enter the bearing. Personally, it is also related to the uneven bearing load capacity caused by the excessive caster angle (4.67 degrees) in Qi Jun design. The solution is to replace the plane bearing. Now the improved version of plane bearing is "ground covering". The improvement is that the upper edge of bearing bottom shell covers the upper shell of bearing from the outside to stop the dust and splashing water raised by wheels. The prototype is "the sky covers the ground", and the gap of the shell faces down to the tire, which is easy to enter the ash and water.

2, 40 kilometers roared by. The common phenomenon in Qi Jun is that the front of the vehicle sounds like a horn, especially when the speed is 40 kilometers per hour. It is obvious when the accelerator is released, but there are also cases of stepping on the accelerator. At present, there is no official explanation from Japanese manufacturers. According to 4S, it is the sound of reduction gear in CVT, and some people say that CVT steel belt and pulley are slightly loose. However, the MT Junyou column also reflected this problem. The hacker forum made an investigation and found that MT howled a lot. But the new car didn't have this phenomenon, just after a while. At present, no substantial damage has been found to the vehicle, so it is not recommended for individuals to replace the gearbox.

3.CVT temperature protection. There are low temperature protection and high temperature protection. The phenomenon is that the engine speed is limited and the accelerator pedal can't reach 2000 rpm. Low temperature protection generally occurs at MINUS 5 degrees or even colder, and it is normal after jogging and hot running. High temperature protection usually occurs during continuous high-speed driving (driving at a speed of 150 for a long time). The reason is that CVT is sensitive to oil temperature, so protective measures are taken to reduce the failure rate. The solution to low temperature protection is to slow down the hot car in winter. The way to avoid high temperature is not to drive too fast.

4.CVT oil seal leaks oil. Several boxes were found on this altar. There are many oil leakage faults in CVT oil seal. After the successful rights protection of Xiaoyao Tour, Dongri extended the warranty of CVT to 654.38+10,000 kilometers for three years, followed by our Qi Jun. The solution is to replace the oil seal.

5, the oil meter is missing a grid. Common problems in Qi Jun before 20 12. The phenomenon is that after filling up the oil, a space is also missing. Personally, I think the reason is that the design is unreasonable, and gasoline impurities pollute the resistor of the oil level meter. The new type oil meter with model 20 12 solves this problem. If the old model is only missing one grid, it is not recommended to repair and replace it.

6. Oil leakage from the dust cover of the transmission shaft. The common faults of most front wheels in Qi Jun are due to the quality problems of dust jacket clamps. It is said that the new car has been improved now. The solution is to replace the clamp if a large amount of oil leakage is not found in time.

7. Qi Jun CVT version, P gear is locked. The phenomenon is that the gear lever cannot be shifted from P gear to other gears. The reason is that the "parking position switch" in the shift assembly is faulty, and the switch cannot be replaced separately in the 4S shop. The maintenance solution is to replace the shift assembly.

8. Abnormal braking sound. The common phenomenon in Qi Jun is a "click" sound when stepping on or releasing the brakes, or a "rumble" sound when the brakes are about to stop, especially when stepping on the brakes in reverse. The reason is that there is a gap between the Qi Jun brake pad and the shrapnel behind it. The temporary solution is to apply butter to several contact points between the back of the brake pad and the shrapnel. This problem will not affect the braking function.

9. Wear and oil leakage of the rear shock absorber. Qi Jun's rear shock absorber is easily damaged. Personally, this is not only related to the quality of shock absorber, but also related to the structural characteristics of Qi Jun rear suspension. It is said that the new car has changed the brand of shock absorber and improved it. The solution is to replace the damaged shock absorber.

10, slow window opening. The phenomenon is that when the window is opened and then closed at low temperature, the window barely rises, especially on the co-pilot side, and even the window cannot be raised. The reason may be related to the low temperature resistance and compactness of the rubber strip material after hardening, and also to the low power of the window-lifting motor. It is said that the new car has changed the window tape and improved it. For the old model, it can be improved after cleaning the lubricating strip. At the same time, operating the same window-raising button of the main driver and the assistant driver can also speed up the window-raising speed of the assistant driver. In addition, TX also reflects that the glass in Qi Jun is too thin, much thinner than that in Teana.

1 1, abnormal sound on the front windshield. The lower end of the front windshield creaked when driving. The reason is that the rubber strip of the front windshield is of poor quality, the seal is not tight, or something dirty has entered the plastic beads at the lower end. It may be inside or outside the glass. It is said that it is very common outside. The gap between the plastic bead at the lower end of the outer side and the glass is easy to be stained with dirt such as sand, and the abnormal sound may be improved after being cleaned by an air pump.

12. Skylight problems: including motor failure that causes the skylight to fail to open and close, skylight drain pipe blockage that causes skylight leakage, rubber strip materials in front of and behind the skylight that can't withstand low temperature, and friction noise when driving after hardening. There are also sealing strips reflecting the left and right borders of the skylight, which are of poor quality, unstable installation and easy to fall off.

13, the throttle is too dirty. In areas with poor air quality, Qi Jun throttle is more sensitive to dirt than most cars. The phenomena are unstable idle speed, occasional jitter and car jam, and even the engine warning light is on. The solution is to clean the throttle. In addition, this column also has an example of replacing the intake valve assembly due to throttle failure.

14, CVT version of Qi Jun, with high fuel consumption during short-distance driving in winter. Any short-distance driving in winter will definitely cost oil, but under the same conditions, CVT Qi Jun is more obvious than ordinary fare oil. When driving on a long road, Qi Jun's CVT version has fuel-saving advantages compared with ordinary cars. Personally, I think the reason is that CVT is sensitive to oil temperature, and warming up needs to consume more heat.

15, the warning light is on. Qi Jun is very common. During driving, the skid warning light, VDC OFF light, ABS warning light and brake warning light are all on (individually or in multiple), and some of them are restarted normally after stopping and turning off the engine. There are many possibilities for this fault. If it is on all the time, it is recommended to go to 4S for inspection.

16, abnormal noise of engine belt. Qi Jun is very common. The belt group makes a metal "scratch" sound or a cricket-like sound. Sprinkling water on the belt will eliminate it, but it will ring again after drying. It may be related to the failure of the tensioner of the belt group. If the noise is not big, you can always observe it. If the noise is too loud, or the belt swings from side to side in the belt groove, it may be that the tensioner has a serious fault and needs to be inspected and replaced in 4 s. The belt tensioner fault is common in Qi Jun, which may lead to belt looseness, jitter and even wear dislocation due to insufficient tension.

17, the inside of the rear wheel is eccentric. Qi Jun is very frequent, but it is not serious. Personally, it is related to the structural characteristics of Qi Jun rear suspension and the camber of rear wheels. If it's not serious, it's okay.

18, the tire is fine. It is easy to hurt tires if you walk badly. Personally, it is related to the thin tire wall. As for whether there is improvement after 20 12, there is no relevant information at present.

19, the horn line is easily broken (whistle horn). It may be because its position just faces the grimace at a certain angle. When washing the car, it is easy for high-pressure water to spray on the grimace and rush to the root of the horn line.

20. There is abnormal noise in the engine compartment. The collision sound is caused by the incorrect position of the front cover lock. By adjusting the spiral support pad of the front cover up and down, the abnormal sound is eliminated.

2 1, the brake disc has abnormal noise. Cars with TX rattle when driving. After 4S inspection, this is caused by the deformation and friction of the brake disc caused by a small piece of iron on the fixed brake caliper. Just correct it with pliers.

22. Abnormal sound of the chassis. The chassis sometimes makes a loud noise when driving, which is caused by the vibration of the heat insulation baffle on the exhaust pipe after inspection.

23. When the throttle is low, there is a buzzing drag. No new car. After a while, it appeared. Some people think it has something to do with CVT, but it is found that the throttle is neutral, which is related to the speed. It is speculated that it is related to the engine, and some of it is improved after replacing all synthetic oil.

24, start the lighter is not smooth. TX reflection Qi Jun's engine ignition is not as good as other cars.

25, the original anti-freezing performance is not good. Northeast TX reflected that the original antifreeze stopped flowing at -27 degrees, which caused the heating system not to circulate for a long time. The freezing point of antifreeze detected by 4s shop was only -20 degrees.

26, the car paint is soft. TX reflected that the car was washed by computer and the body was swept out by electric mop. TX reflects that walking on the wild road is too easy to be scratched by bushes.

27, CVT version, low reverse torque. The reverse speed ratio of ordinary cars is the largest, but the reverse speed ratio of CVT Qi Jun is only 1.75: 1, which is far less than the highest speed ratio of D gear 2.349, resulting in a relatively weak reverse speed ratio. The solution is to avoid putting in reverse gear as much as possible to get out of trouble. When it is necessary to get out of trouble in reverse gear, it is helpful to turn off VDC and open the lock. MT version does not have this problem.

28. The battery is not maintenance-free. It is recommended to check the liquid level regularly.

29, intelligent key's anti-interference ability is poor, occasionally failure. Some can be improved by replacing batteries or cleaning key electrode contacts.

30, TX reflects that the new car smells big and stubborn. Personally, I think it's good if it's not formaldehyde.

3 1, TX reflects that the hand brake is not very effective and it is easy to slide down the slope. Personal experience is that Qi Jun handbrake has a long stroke, so it feels loose. When parking on a steep slope, tighten it hard to make the ratchet ring rotate for more than 7 times.

32. The trunk door is not easy to close, especially for new cars. Part of the reason is the closed air pressure. If the window is opened after the test, it is not easy to close the tailgate. It is said that it can be improved by adjusting the rubber pad on the frame of the tailgate.

33. The glass kettle leaks at the joint between the kettle body and the kettle neck. Common diseases. Your design can't fill the water so full.

34. Occasionally I can't open the door from the outside. Low temperature and car washing make the door easy to get water. It seems that the right back door is more likely to happen.

35, engine corner cylinder gasket oil leakage. In fact, many brands of cars have had this problem, and it doesn't matter if it doesn't reach the level of liquid leakage.

Automobile pump piston can't rebound. The abs pump is also faulty. Supplement: The landscape of the 70th floor reflects the deformation of the brake disc.

36. The lower part of the back door is too narrow, and the old man will touch his feet when getting on and off the car. Design style problem. The advantage is that the probability of water leakage at the back door is reduced when crossing the water.

37. The blind spot of sight is large. The design of the slope and width of A-pillar makes the blind area in front of the side bigger when turning, especially when going downhill along Panshan Highway, when it is necessary to focus on the front of the side, the visual field is insufficient. The C-pillar blocks the vision of the rear corner too much, which affects the reversing, and the lighting of the reversing lamp is not enough at night. There is a dead zone of about 10cm between the running area of the front wiper and the left A-pillar, and the mud scraped by the rain and the A-pillar are superimposed on the left front to form a large visual blind zone.

38. The exposed area of the front lower part of the locomotive is large, and there is no grille protection. On one occasion, when TX was off-road, the air conditioner condenser was broken by a falling stone. Solution: install a protective net, Taobao also has it, and search it yourself.

39.TX reported that the noise was too high when the speed exceeded140km. Then don't overspeed.

40, exhaust muffler corrosion. All cars will rust, but some TX questioned that Qi Jun rusts faster than ordinary cars.

4 1. The buckle of the sealing strip at the lower edge of the door is loose, which makes the sealing strip easy to fall off.

42. Circuit failure. Part of the reason is that the quality of plugs used in Qi Jun circuit seems to be not high. The trunk 12 volt power supply is dead, and the airbag hairspring harness is faulty. In addition, after the vehicle is started, the dashboard backlight and tachometer do not work. After 4S inspection, it is the contact problem of the tail of the instrument panel socket, just pull it a few times with thin wire.

43.TX reflects that the rear seat cannot be reset after it is turned up. After 4S inspection, the circlip is broken. In addition, some rear seat adjustment fixing bolt holes were loose abnormally, which was improved after being wrapped with cloth. No. vest 1 on 26th floor supplement: the rear seat and trunk are prone to make abnormal noises.

44.TX reflected that the cruise crashed and the speed could not be fixed. Recovery after flameout and restart.

45.TX is reflected in the hillside road, which is burnt after using AUTO for a long time, and tasteless after using 2WD. It also reflects that there is a burning smell on the hillside road for a long time after 2 weeks, excluding the smell of tires and suspecting that it is the smell of four-wheel drive clutch. When AUTO goes bad, TX reflection with 4 driver protection appears. There is a TX that reflects the sudden direction deflection of vehicles on the expressway in AUTO mode in rainy days.

46. The shift indicator light on the shift lever has gone out. The reason is that the light bulb indicating the gear position is not a cold light source, and it will be hot and baked when the light is turned on at night. This book is not worth mentioning, but it reflects a lot of TX, so it is included.

47. The air conditioner can smell the smell outside the car when it is in internal circulation. It may be to prevent people from lack of oxygen in the car and maintain micro-airflow circulation with the outside of the car.

48, fuel tank door lock failure. The fuel tank door won't open.

49. The engine burns oil. It is rare to burn engine oil in Qi Jun, with a serious consumption of engine oil per 1000 km/liter.

5 1, air conditioning compressor failure. An example. One of them was repaired because of too much noise, and it was found that the bearing of the air conditioner compressor was faulty. There is also a case where the compressor of outdoor air conditioner failed in summer and could not be cooled.

52. When the turn signal is turned on, the steering wheel is stuck on the lamp post. TX said that the lubrication was improved after disassembly.

53. The original rubber of tire valve is of poor quality, easy to age and crack quickly.

54. The gasoline pump under the back seat has a loud buzz.

55. The engine water tank leaks. An example.

56. After the new car arrives, the battery terminal is often not tight and the tire pressure is too high. This is because in the process of transportation and inventory of new cars, in order to prevent battery emptying and tire deflation, it is often necessary to remove the negative electrode of the battery and set the tire pressure to 3.0. At the time of delivery, 4S personnel may have accidentally failed to tighten the battery terminal and adjust the tire pressure. Check it out for yourself, riders.

57. 10 Extreme Edition Qi Jun's navigation integrated machine has quality defects and the touch screen is out of order. When handwriting and pinyin are input on the screen, the pointer jumps, and the screen has no calibration function, resulting in normal input; Cannot exit after navigation starts; This map is too old; Before model 20 12, the original navigation only supported a memory card with a maximum of 2G, which affected the normal update. You have to ask a computer expert to help you delete some files before updating, but 4S doesn't provide this service, which leads to your promise of updating navigation software for free for two years when you buy a car.

58, electronic powertrain failure. The phenomenon is that there will be a continuous click in the direction of fast release, which is especially obvious when the car is cold and the weather is cold. However, the problem of plane bearing is ruled out. It was confirmed by 4S shops and manufacturers that the electronic power-assisted assembly failed and could not be repaired, so the assembly could only be replaced. It was imported from Japan and the material cost was more than 7,000 yuan.
